The fifth graph shown was a knockout.
To get what looks like an 80% + correlation between two disparate data series [relative supernova rate and [numbers of] marine invertebrate genera] is very impressive.
There would have to be distorting information [inaccuracies] in the underlying data series, and there might well be other influences such as solar activity.
I am sure the experts [which do not include yours truly] will be looking at the underlying data very carefully!
One [or more] Nobel prizes for Svensmark?

Reading this paper will be a weekend project for me. Very interesting conclusion if it bears the weight of scrutiny.

The paper has surfaced again - I don't know if this is a revision or just someone noticing now the 'climate' for the paper is more acceptable... calderup.wordpress.com/2012/04/24/a-stellar-revision-of-the-story-of-life/A stellar revision of the story of life Climate Change: News and Comments and The Svensmark Hypothesis
Svensmark’s Cosmic Jackpot
Visible to the naked eye as the Seven Sisters, the Pleiades are the most famous of many surviving clusters of stars that formed together at the same time. The Pleiades were born during the time of the dinosaurs, and the most massive of the siblings would have exploded over a period of 40 million years. Their supernova remnants generated cosmic rays. From the catalogue of known star clusters, Henrik Svensmark has calculated the variation in cosmic rays over the past 500 million years, without needing to know the precise shape of the Milky Way Galaxy. Armed with that astronomical history, he digs deep into the histories of the climate and of life on Earth. I think that Svensmark and Shaviv are likely to be the names remembered in the future. |

UV rays are from sun, right? and whenever suns enters a series of weak cycles UV impact declines, is it so? And that is time when we are likely to get over dosis of cosmic rays? Did I got that right? |

UV rays are from sun, right? and whenever suns enters a series of weak cycles UV impact declines, is it so? And that is time when we are likely to get over dosis of cosmic rays? Did I got that right? Correct. The theory is that the sun goes quiet and two things happen: UV reduces which leads to cooler oceans and less ozone at height _and_ the weakend solar wind results in more galactic cosmic rays reaching the Earth's atmosphere where they break up on collision with molecules in the atmosphere and the remains of the collisions act as 'cloud condensation nucleii' leading to more clouds which raise the Earth's albedo (reflect more sunlight) which _also_ cools the Earth. A kind of double whammy. But it gets more complicated as the oceans are cooler the convective cells at the equator reduce and the jetstreams become more meridonal and loopy therefore longer - and that _also_ increases cloud cover. A _triple_ whammy. So the Sun going quiet is not really good news. (Speaking from minus 23C Montreal rather than plus 23C Florida  ) |

I know cutty posted this but I wanted to put it into its repository for future reference. "Svensmark’s cosmic ray theory of clouds and global warming looks to be confirmed" "From a Technical University of Denmark press release comes what looks to be a significant confirmation of Svensmark’s theory of temperature modulation on Earth by cosmic ray interactions. The process is that when there are more cosmic rays, they help create more microscopic cloud nuclei, which in turn form more clouds, which reflect more solar radiation back into space, making Earth cooler than what it normally might be. Conversely, less cosmic rays mean less cloud cover and a warmer planet as indicated here. The sun’s magnetic field is said to deflect cosmic rays when its solar magnetic dynamo is more active, and right around the last solar max, we were at an 8000 year high, suggesting more deflected cosmic rays, and warmer temperatures. Now the sun has gone into a record slump, and there are predictions of cooler temperatures ahead This new and important paper is published in Physics Letters A. – Anthony Danish experiment suggests unexpected magic by cosmic rays in cloud formation Researchers in the Technical University of Denmark (DTU) are hard on the trail of a previously unknown molecular process that helps commonplace clouds to form. Tests in a large and highly instrumented reaction chamber in Lyngby, called SKY2, demonstrate that an existing chemical theory is misleading." link |
